Sputtering at startup

Bad news... No luck

So, got some cleaner and carefully cleaned the throttle body as demonstrated in the pics .... but the darn thing is still sputtering at morning startup. :mad:

the RPMs arent even at a full 1...it sputters a little, then revs up to about 1 1/2 then rests at 2...

any ideas?
 
I'd take it back to the dealership and tell em its still doin and - cuz its an 05 and I know the warranty is running out.
 
sooo frustrating!~~ I just called and they arent able to schedule service for me until 8/4!!~~ said the tech is on vacation next week and this week is full so I guess I'll have to leave it until then.
 
I would first try a reset using the 'consult'. Possible that Your TB may be going bad. Nissan had problems with them, & now offer a remanuf. TB that could work better.
 
hey man, don't mean to harp on this cleaning, but did you open the butterfly & clean about an inch into the opening? usually a ridge of deposits builds up there, also on the butterfly itself, it can build up a ridge on the edges... you need to clean the inner edges of the butterfly too... the face of the butterfly shown in this pictures has no bearing on the function hear, it's the inner edges that really need to be cleaned, incase I didn't make that clear enough.

the throttle opening at idle is very small, it doesn't take much to build up enough edge to reduce that flow...

usually if the problem is something else it would show a fault as a CE light, if you're sure it's cleaned well on the inside too then it needs a proper diagnosis I would say, but I would double check the buildup before giving up, unless you know you did it well enough...
 
sounds like a stupid question because iv'e never done it or actually looked at how to take it off, but how do you take off the tb cover?
